usim

minimal discrete time simulation in javascript

API

Get the uSim class by var uSim = require("usim"); (node) or define(["usim", ...], function (uSim, ...) { /*module code*/} (AMD). If needed, you can also just include it in <script src=".../usim.js"></script> and use the global uSim.

  • var usim = new uSim() Creates new simulation timeline with initial time set to -Infinity.

  • usim.schedule(time, object) Schedules object to occur at time.

  • usim.time The current simulation time.

  • usim.peek() Returns the object that is scheduled to earliest time or null. If the object's time is higher than current time, the current time is shifted accordingly.

  • usim.peek(cb) Same as usim.peek(), but instead of returning the object, it calls the callback with the object or null as the only argument.

  • usim.peekUntil(time) Same as usim.peek(), but if time of object if bigger than time, null is returned instead and object stays in the schedule.

  • usim.peekUntil(time, cb) Same as usim.peek(cb), but if time of object if bigger than time, null is passed instead and object stays in the schedule.

  • usim.stream(cb) Calls cb with all scheduled objects, as if usim.peek(cb) was called in loop while there are some scheduled objects.

  • usim.streamUntil(time, cb) Same as usim.stream(cb), but quits if time would be shifted past time (IOW: streams all objects scheduled up to time).

  • usim.run() Same as usim.stream(function (each) { each(usim) }). IOW, treats all scheduled objects as functions and calls them, passing itself as the parameter.
